Abstract
(EN)
A transition metal complex which comprises a transition metal belonging to one of the groups 8-10 and a ligand represented by general formula (1), said ligand being bonded to said transition metal via a coordinate bond; a phosphorescence emitting material which comprises the transition metal complex; and, as an example of the use of said transition metal complex, an organic electroluminescence device provided with a pair of electrodes and at least one organic layer including a layer, said layer being positioned between the electrodes and containing a phosphorescence emitting material which comprises the transition metal complex. In general formula (1): R1 and R2 independently represent a substituent; m and n independently represent an integer of 0-4; Z represents a functional group having a Hammett substituent constant (σp) of 0-0.8; and # represents the position of the coordinate bond to the transition metal.
